We recently hardened Git for Windows by ignoring `C:\ProgramData\Git\config` files unless they are owned by the system account, by the administrators group, or by the account under which Git is running. Turns out that there are situations when that config file is owned by _an_ administrator, not by the entire administrators group, and that still is okay. This can happen very easily e.g. in Docker Containers. Let's add a fall back when the owner is none of the three currently expected ones, enumerating the members of the administrators group and comparing them to the file's owner. If a match is found, the owner is not dubious. Enumerating groups' members on Windows is not exactly a cheap operation, and it requires linking to the `netapi32.dll`. Since this is rarely needed, and since this is done at most a handful of times during any Git process' life cycle, it is okay that it is a bit expensive. To avoid the startup cost of linking to yet another DLL, we do this lazily instead: that way, the vast majority of Git for Windows' users will not feel any impact by this patch.

Git for Windows
This is Git for Windows, the Windows port of Git.
The Git for Windows project is run using a governance model. If you encounter problems, you can report them as GitHub issues, discuss them on Git for Windows' Google Group, and contribute bug fixes.
Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of core Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites. The core git mailing list is plain text (no HTML!).
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
